Title: Manufacture of honeycomb filter
Inventor: MIWA NAOTO
IPC: B28B1/52
Filed: 1981-07-03
Abstract: PURPOSE:To heighten trap ratio of particulate and to depress increase of pressure loss by increasing gas permeability of wall of a honeycomb structure and making the surface layer exceedingly porous. CONSTITUTION:Cordierite fiber, methyl cellulose, water and lubricant are mixed and kneaded. A honeycomb structure is extruded using a mold that extrudes the mixture, and dried after cutting. Next, the dried product is heated to burn up methyl celllulose and wax, and calcined until the cordierite fibers are sintered together. After cooling, the honeycomb filter thus obtained is held in a metallic case 5 through a metallic heat resisting cushion and made to form a trapper. Consequently, trap ratio of particulate can be heightened and a small-sized filter  can be designed easily.

Filed: 1993-04-30
Abstract: PURPOSE:To provide a GaAlAs semiconductor light emitting element of high humidity resistance wherein high output can be acquired even if AlAs mixed crystal ratio is restricted in both sides of an element. CONSTITUTION:After growth melt solution 9 of a lower layer is brought into contact with a GaAs substrate 13 by partitioning a first bath 1a for forming a first clad layer in an epitaxial boat by a partition 4 up and down, a temperature is lowered by melt back and a GaAlAs first clad (a) layer of low AlAs mixed crystal ratio is formed in a growth starting surface of the GaAs substrate 13. Thereafter, the partition 4 is removed and growth melt solution 10 is brought into contact with the GaAs substrate 13 to form a conventional GaAlAs first clad layer (b) layer. Humidity resistance and high output are ensured regardless of AlAs mixed crystal ratio in both sides of an element after removal of the GaAs substrate 13 by forming the first clad layer to the two layers of the first clad (a) layer of low AlAs mixed crystal ratio and the first clad (b) layer of high AlAs mixed crystal ratio in this way.

Title: Oscillator of pll constitution
Inventor: ITAYA EIJI
IPC: H03L7/183
Filed: 1980-07-30
Abstract: PURPOSE:To avoid the change in noise band width when the frequency dividing ratio and the output frequency are changed, by using a voltage controlled oscillator having the characteristics increasing the voltage-frequency conversion gain. CONSTITUTION:An oscillation angular frequency omegan when the specific oscillation number of an oscillator of PLL constitution is assumed to be continuously oscillated, is expressed as omegan=(k0 kd/tau1N)<1/2>, (wherein kd is the conversion gain of a phase comparator, k0 is voltage-frequency conversion gain of VCO, tau1 is a value relating to the low pass filter element, and CR1, N are frequency dividing ratio). The kd, tau1 are kept constant and k0 is changed with the frequency dividing ratio N. In this case, by changing the voltage-frequency characteristic of the voltage controlled oscillator VCO as indicated in the Figure, the change in noise band width can be avoided, when the output frequency is changed through the change in the frequency dividing ratio in the oscillator of PLL constitution.

Patent JP-S59231777-A (JP)
Title: Inter-track detector
Inventor: ISHIBASHI HIROMICHI
IPC: G11B21/08
Filed: 1983-06-13
Abstract: PURPOSE:To avoid the deterioration of reliability for the detection of a track even at a high-speed detection mode by driving a pulse generating means with the edge of a read reproduction signal undergone the shaping of waveform at a level higher than the threshold value only when the reading position exists on a track and therefore attaining the expression in a binary form. CONSTITUTION:A waveform shaping means 100 has the prescribed threshold value with a voltage source 300. A single pulse generating means 200 is driven by the edge of the output signal of the means 100. In case the reading position is set between the tracks, no signal is delivered since the level of the means 100 does not exceed its threshold value. In this case, the output potential is reset to its original level to detect an area between tracks in case the time taut is longer than the duration time taup of the pulse generated from the means 200. The read reproduction signal does not act as noise since it is changed into a rectangular wave. Thus the track can be retrieved at a high speed. The signal is produced once when an area between the tracks is crossed. Thus it is possible to detect the area between the tracks with high reliability.

IPC: H03J3/14
Filed: 1986-05-08
Abstract: PURPOSE:To prevent a tuning display light emitting diode from being blinked by making the lighting band narrow when an FM receiver is in the channel selecting operation based on the control output of a control circuit, turning off an AFC circuit and making the lighting band broad and turning on the AFC circuit in the tuning state. CONSTITUTION:When the receiver is in the channel selection state, since a display drive signal output terminal 8 of an IC 4 is at an H level, a transistor (TR) 10 is turned off. Then the display band of the tuning display light emitting diode 11 depends only on a resistor 13, the light band is made narrow and the AFC circuit 16 is turned off. When the channel selection is progressed and the frequency is tuned to a broadcast frequency, since the display drive signal output terminal 8 of the IC 4 is at an L level, the TR 10 is turned on. Then the display band of the tuning display light emitting diode 11 depends on the combined resistance of resistors 13, 14 to make the light band broad. Further, a DC voltage smoothed by a capacitor 21 of the AFC circuit 16 is fed to a front end 2 via resistors 18,19 to apply the automatic frequency control.

Abstract: PROBLEM TO BE SOLVED: To reduce impacts generated in pressure-fed fuel and to improve resolution of pressure-feeding amount of fuel by giving a profile to a pump drive cam so as to moderate a plunger lift speed before a press-feeding top death center. SOLUTION: A pump drive cam 77 for lifting a plunger 83 of a fuel supply pump 80 has a cam profile 78 in which a rotation angle range θe corresponding to a pressure-feed stroke of the plunger 83 is wider than a rotation angle range θi corresponding to a suction stroke of the plunger 83 and a lift speed of the plunger 83 per rotation angle of a pump drive shaft 77a is slower than a drop speed of that. Impacts given to fuel during fuel pressure-feed period is reduced to suppress vibration and noise of the fuel supply pump 80. Resolution of fuel pressure-feed amount during the pressure-feed stroke is thereby improved.

Title: Video signal processing circuit
Inventor: HASHIMOTO JUNJI
IPC: H04N9/44
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To generate a stable clock signal even when the quality of a display video is deteriorated by maintaining a control voltage for a voltage controlled oscillator constituting a phase locked loop at the control voltage before deterioration. SOLUTION: A system clock generating part is provided with a deterioration detecting part 107 which detects the deterioration of an input picture signal, and outputs a latch signal to a latch part 106 in a deteriorating period so that an input signal to a voltage controlled oscillator 101 can be latched. When a deterioration is present in an input picture signal, the deterioration detecting part 107 of the input picture signal generates a latch control signal based on the deterioration of the input picture signal as a latch section. Therefore, the generation of a clock is stabilized by the system clock generating part.  Thus, even when the input picture signal is deteriorated, that is, even when color burst signal components or synchronizing signal components included in the input picture signal are deteriorated, the extraction of a color burst signal being a reference signal for demodulating a chrominance signal can be satisfactorily operated, and color reproducibility can be improved.
